/**
 *
 * The test checks up the methods of <code>com.sun.jdi.EventRequest</code>: <br>
 *     1. <code>putProperty(Object, Object)</code>                          <br>
 *     2. <code>getProperty(Object)</code>                                  <br>
 *     3. <code>setSuspendPolicy(int)</code>                                <br>
 * to correctly work for boundary values of argument.                       <br>
 *
 * The test performs the next testcases:                                    <br>
 *     1. <code>putProperty(null, String)</code> - in this case it is
 *        expected property <code>null</code> with value of
 *        <code>String</code> will be created.                              <br>
 *        No exception must be thrown.
 *     2. <code>getProperty(null)</code> - value of <code>String</code> from
 *        the previous case is expected as return value. No exception must
 *        be thrown.                                                        <br>
 *     3. <code>setSuspendPolicy(int)</code> is checked for the next
 *        parameters: <code>Integer.MIN_VALUE</code>, <code>-1</code>,
 *        <code>Integer.MAX_VALUE</code>. IllegalArgumentException is expected. <br>
